Although much of its discovery process is descriptive and qualitative, chemistry is fundamentally a quantitative science. It serves a wide range of human needs, activities, and concerns. The mathematical sciences provide the language for quantitative science, and this language is growing in many directions as computational science in general continues its rapid expansion. A timely opportunity now exists to strengthen and increase the beneficial impacts of chemistry by enhancing the interaction between chemistry and the mathematical sciences.

Algebra is a wonderful tool for testing and predicting our understanding of the world. The Xs, Ys and Zs in the algebra mean something real. Algebra lets us take a word description of the world and change it into a mathematical description which is really useful. Clothing designers use algebra to work out how best to cut cloth, engineers use algebra to design cars, boats and aeroplanes and the next generation of medicines customised to our genetic individuality will use algebra. Plumbers and carpet fitters use algebra to work out how to cut pipes or carpets to fit a space...

Axial Flux PermanentMagnet (AFPM) machine is a multivariable object due to its multivariable mathematical model which is defined by the matrix equations: voltage equation, flux equation, torque equation and motion equation. Especially, the complex inductance matrix in the machine’s mathematical description causes difficulties in analyzing to build its mathematical model. This paper proposes a method of applying perpendicular transformation to simplify the machine’s model to help the design of controller easier.

Before entering into the different techniques of optical metrology some basic terms and deﬁnitions have to be established. Optical metrology is about light and therefore we must develop a mathematical description of waves and wave propagation, introducing important terms like wavelength, phase, phase fronts, rays, etc. The treatment is kept as simple as possible, without going into complicated electromagnetic theory.

We study enhancement of diﬀusive mixing on a compact Riemannian manifold by a fast incompressible ﬂow. Our main result is a sharp description of the class of ﬂows that make the deviation of the solution from its average arbitrarily small in an arbitrarily short time, provided that the ﬂow amplitude is large enough. The necessary and suﬃcient condition on such ﬂows is expressed naturally in terms of the spectral properties of the dynamical system associated with the ﬂow. In particular, we ﬁnd that weakly mixing ﬂows always enhance dissipation in this sense. ...

Moir´ Methods. Triangulation e Figure 3.2 is an illustration of two interfering plane waves. Let us look at the ﬁgure for what it really is, namely two gratings that lie in contact, with a small angle between the grating lines. As a result, we see a fringe pattern of much lower frequency than the individual gratings. This is an example of the moir´ effect and the resulting fringes are e called moir´ fringes or a moir´ pattern. Figures 3.4, 3.8 and 3.9 are examples of the same e e effect. The mathematical description of moir´ patterns resulting from the superposition e...

Introduction: Most electrochemical reactions take place at the interface of two or more phases. Hence the area of reaction plays a vital role in determining the efﬁciency of an electrochemical process, just like in any surface reaction. There are several ways to increase the available area for reaction in an electrochemical cell: multiple electrodes are stacked alternatively, bipolar electrodes are used, and, sometimes, the reaction surface is modiﬁed by etching or coating with large surface area particles. ...

There are few physical phenomena so generally studied which are as misunderstood as the phenomenon of flight. Over the years many books have been written about flight and aeronautics (the science of flight). Some books are written for training new aeronautical engineers, some for pilots, and some for aviation enthusiasts. Books written to train engineers often quickly delve into complicated mathematics, which is very useful for those who wish to make detailed calculations.

In this paper we introduce a method for partial description of the Poisson boundary for a certain class of groups acting on a segment. As an application we ﬁnd among the groups of subexponential growth those that admit nonconstant bounded harmonic functions with respect to some symmetric (inﬁnitely supported) measure µ of ﬁnite entropy H(µ). This implies that the entropy h(µ) of the corresponding random walk is (ﬁnite and) positive. As another application we exhibit certain discontinuity for the recurrence property of random walks. ...

The goal of this paper is to describe all closed, aspherical Riemannian manifolds M whose universal covers M have a nontrivial amount of symmetry. By this we mean that Isom(M ) is not discrete. By the wellknown theorem of MyersSteenrod [MS], this condition is equivalent to [Isom(M ) : π1 (M )] = ∞. Also note that if any cover of M has a nondiscrete isometry group, then so does its universal cover M . Our description of such M is given in Theorem 1.2 below. The proof of this theorem uses methods from Lie theory, harmonic maps,...

Having discussed individual components of industrial servo drives from an operation point of view and a mathematical descriptive point of view, the next step is to combine these components into a block diagram for the complete servo drive. The block diagram is a powerful method of system analysis. In the block diagram each component in a servo system can be described by the ratio of its output to input. Thus the output of one component is the input to the next component.

Such jobs would then be gone, to be replaced by jobs requiring much more sophisticated mathematical training. The mathematics needed for these machines, as was case with engines, has been the main impediment to actual widescale implementation of such robotic mechanisms. Recently, it has become clear that the key mathematics is available, (the mathematics of algebraic and geometric topology, developed over the last 80  90 years), and we have begun to make dramatic progress in creating the programs needed to make such machines work.

Physical theories allow us to make predictions: given a complete description of a physical system, we can predict the outcome of some measurements. This problem of predicting the result of measurements is called the modelization problem, the simulation problem, or the forward problem. The inverse problem consists of using the actual result of some measurements to infer the values of the parameters that characterize the system. While the forward problemhas (in deterministic physics) a unique solution, the inverse problem does not.
